Checklist: African River Biotope Setup Done Right
Embracing the diversity and beauty of African river habitats is a rewarding challenge for any aquascaping enthusiast. If you want your aquarium to reflect the authentic features of Africa’s rich waterways, this comprehensive checklist will help you do it right. From selecting the right tank size and substrate to choosing suitable fish, plants, and maintenance routines, we’ve covered every aspect to help create a successful African river biotope aquarium.
Why Set Up an African River Biotope?
African rivers, such as the Congo, Niger, and Zambezi, are home to many unique fish and plant species ideal for biotope aquascaping. Replicating these natural environments in your aquarium not only promotes the health of your aquatic life but also delivers a striking, educational centerpiece for your space.

Choose the Right Tank Size
African river biotopes often house active fish species that appreciate swimming space. Aim for a minimum tank size of 120 litres (30 gallons), but larger is even better for showcasing natural behaviors and varied aquascaping layouts. A longer tank layout helps mimic natural riverbanks and provides more room for territory.
Set Up Effective Filtration and Water Flow
Healthy African river biotopes depend on clean water and stable currents. Opt for a high-quality external canister filter with a flow rate matching the tank volume 4-6 times per hour. Arrange the filter outflow or use powerheads to generate a moderate water movement, simulating the current of a real river.
Select Substrate and Decor
- Sand or Fine Gravel: Choose natural-colored sand or smooth gravel to imitate riverbeds. Avoid sharp substrates that could harm bottom-dwelling fish.
- River Stones & Rounded Rocks: Group them to mimic natural rock scattering and create interesting territories.
- Driftwood: African Mopani wood is ideal, both for authenticity and creating shaded refuges for fish.
- Leaf Litter: Almond or magnolia leaves can mimic natural river debris, add tannins, and promote natural behavior.
Pick Authentic African Aquatic Plants
While some African rivers are sparsely vegetated, marginals and hardy aquatic plants thrive along their banks:
- Anubias species: Hardy, shade-tolerant, and easy to anchor on wood or rocks
- Bolgbitis heudelotii (African Water Fern): Ideal for river biotopes
- Crinum natans (Onion Plant): Striking, slow-growing, and authentic
- Vallisneria spp.: Adds a flowing grass effect often seen in river margins
Attach these plants to rocks or wood for a more natural appearance, and avoid introducing non-African species for authenticity.
Choose Compatible Fish Species
Selecting native fish enhances the authenticity and harmony of your biotope:
- Congo Tetra (Phenacogrammus interruptus): Vibrant colors and graceful schooling behavior
- African Butterfly Fish (Pantodon buchholzi): Surface dweller with unique hunting style
- Synodontis Catfish: Various species suit river biotopes and help keep the bottom clean
- Kribensis Cichlid (Pelvicachromis pulcher): Hardy, small, and beautifully colored
- Other options: Distichodus, Alestes, and smaller mormyrids (elephant nose fish)
Make sure tank inhabitants are compatible in size and temperament, and avoid overcrowding.
Install Appropriate Lighting and Heating
- Lighting: Moderate intensity is ideal. Use programmable LEDs to simulate natural daylight. Some rivers have shaded or dappled light — adjust accordingly.
- Heating: African river temperatures are 24–27°C (75–80°F). Use a dependable aquarium heater with a thermometer for accuracy.
Maintain Water Parameters
Stable, soft to moderately hard water is preferred. Aim for:
- pH: 6.0–7.5
- Hardness: 5–12 dGH
- Ammonia and nitrite: 0 ppm
- Nitrate: < 20 ppm

Set a Maintenance Routine
- Weekly water changes: 25–35% of tank volume
- Monitor water parameters: Regular testing is crucial
- Prune plants: Remove dying leaves and excess growth
- Clean substrate: Siphon uneaten food and debris without disturbing plant roots
Consistent upkeep prevents algae blooms and keeps your African river biotope aquarium healthy.
Aquascaping Tips for a Natural River Look
- Arrange substrate and rocks to create slopes and channels, mimicking flowing water
- Use plant groupings to form natural “islands” or margins
- Leave open swimming areas for active fish
- Vary hardscape heights to provide shelter and visual interest
